    Abstract:
    Preoperative localization of parathyroid tissue by selective neck vein catheterization and radiommunoassay of parathyroid hormone (PTH) was used in 18 patients with primary hyperparathyroidism (PHPT), 9 or whom had earlier been subjected to surgical neck exploration. Sampling from large and small neck veins provided localizing data in 11 of 15 patients with parathyroid adenomas. In 3 other patients, diffuse parathyroid hyperplasia was also correctly predicted preoperatively. In 3 patients hyperplasia was found, the surgical procedure was not influenced in a negative way by the failures. Large vein sampling was less helpful then selective small vein sampling. The results show that selective venous sampling from the neck and radioimmunoassay of PTH are valuable preoperative adjuncts to surgical exploration, escpecially in patients who have had previous neck surgery. Since the catheterization procedure is uncomfortable to the patient and difficult for the investigator, its use should be restricted to patients with previous neck surgery, Neck vein catheterization can probably not be used to establish the diagnosis of PHPT in uncertain cases.
